Productive Process


Stretching is a two-part process that uses a hot draw bath. From the creel, the tow goes to a stretcher containing a hot chemical bath of about 60-80 degrees Celsius. 

It is the first drawing. The second drawing occurs in a steam box chest between the second and third stretcher. These chemicals help to stretch the fibers before crimping.


It is a method of achieving irregular shrinkage on fiber. Three things happen to the tow first; cooling, oiling, and stacking together. It then goes to the crimper after pre-heating by passing through a tension roller. The crimper squeezes the fiber to shrink it.

This process adds properties that are useful for staple fiber applications. For example, it adds bulk and wool-like appearance to fabrics.

Cutting and Drying

The tow moves up to a tension stand machine for cutting to create Polyester staple fiber. Passing fiber over the tension stand helps achieve even length when cutting.

They dry the staple fiber by blowing air at high pressure over it on a chain board conveyor. additional, spraying of anti-static solution occurs to avoid clinging to each other when open fibers.


Finally, the dry, treated staple fiber is ready for packaging. It enters the baler chamber for weighing and baling. The machine weighs it, while the staff puts into bales and labels it. The forklift transfers complete bales to the storage for shipping.
